GPS tracking for running Track on all GPS + Multi Setting. 5 x 1km repeats on 400m track. Started one diagonal corner would finish the opposite corner after 2 + 1/2 laps and then walk diagonally across to start next 1km repeat to start finish in same place, for some reason the track has me crossing at the mid section of the track perpendicularly, I never did that, it also automatically considered the first few laps as a warm up and all my in between as rest (which I manually changed to not warm up and from rest to recovery) it also had my 6th recovery lap as 710meters in 2:38km pace when I simply walked diagonally across at a slow pace to start my next 1km lap. Any advice? Gave me a bunch of super fast records that I've had to reject because they are not true.
